Ansible 2.0.0.2 is slow compared to 1.9.4 ?

Hi,

I tried to compare Ansible 2.0.0.2 to 1.9.4 on this VM

client01:/data/ansible # cat /etc/os-release
NAME=openSUSE
VERSION=“13.2 (Harlequin)”
VERSION_ID=“13.2”
PRETTY_NAME=“openSUSE 13.2 (Harlequin) (i586)”
ID=opensuse
ANSI_COLOR=“0;32”
CPE_NAME=“cpe:/o:opensuse:opensuse:13.2”
BUG_REPORT_URL=“https://bugs.opensuse.org”
HOME_URL=“https://opensuse.org/”
ID_LIKE=“suse”
client01:/data/ansible #

using git checkouts as described in

https://groups.google.com/forum/#!searchin/ansible-project/checkout|sort:date/ansible-project/nrQFcW8X1WU/QR7ksJEvBQAJ

I am not a git expert, so probably something went terrible wrong while dealing with git and I broke 2.0.0.2 as it seems
to be slow and failed to run the modul setup:

a)
Run < ansible localhost -a “ls -al /etc/hosts” >
Result: 1.9.4 takes 1.09s, 2.0.0.2 takes 10.3s.

Ansible version: 1.9.4

client01:/data/ansible # time ansible localhost -a “ls -al /etc/hosts”

b)

The ansible command fails due to a timeout in “cmd”: “/usr/bin/lsblk -ln --output UUID /dev/sda2”

This command runs fine on the cli:

client01:/data/ansible # time /usr/bin/lsblk -ln --output UUID /dev/sda2
